DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a front view showing the schematic configuration of a clinical sample analysis apparatus 1 according to an embodiment of the present invention.

As shown in FIG. 1, the clinical sample analysis apparatus 1 of this embodiment includes measuring units 21, 22 and 23 which are blood cell counting devices, an information processing unit 3 and a sample transport device 50. For example, the measuring unit 21 measures blood and obtains measurement data for calculating the number of white blood cells (WBC), red blood cells (RBC) and platelets (PLT) and the like. The information processing unit 3 has a function of obtaining the analysis result by processing the measurement data output from the measuring units 21, 22 and 23. The sample transport device 50 automatically supplies samples to the measuring units 21, 22 and 23 by an instruction from the information processing unit 3. The information processing unit 3 has a personal computer and is connected to the measuring units 21, 22 and 23 via a communication cable 3 a so as to communicate therewith. The sample transport device 50 includes a sample input unit 51 which stores sample racks in which measurement has not yet been performed, transport units 52 a, 52 b and 52 c for transporting sample racks containing samples to the measuring units 21, 22 and 23, and a sample storage unit 53 for storing sample racks in which measurement has been performed. The transport unit 52 a includes a transport passage 521 a for transporting samples, which are to be measured, to the measuring unit 21, and a transport passage 522 a for transporting samples, which are not to be measured by the measuring unit 21, to the transport unit 52 b or 52 c or the sample storage unit 53. Each of the transport units 52 b and 52 c has the same configuration as that of the transport unit 52 a.

In upper right portions of the front faces of the measuring units 21, 22 and 23, light-emitting sections 21 a, 22 a and 23 a are provided for identifying each of the measuring units by color. The respective light-emitting sections 21 a, 22 a and 23 a have a three-color LED. The three-color LED is embedded with a red-color LED chip (R), a green-color LED chip (G) and a blue-color LED chip (B) in one package. As the three-color LED, for example, the trade name “full color LED (type name: NSTM515)”, manufactured by Nichia CORPORATION, can be used.

FIG. 2 is a block diagram showing the configuration of the measuring unit 21. The measuring unit 21 includes a specimen supply section 4, a WBC detection section 5, a RBC detection section 6, a HGB detection section 7, a control section 8, a communication section 9, an LED driving circuit 10, the light-emitting section 21 a and a sensor 11. In this embodiment, each of the measuring units 22 and 23 has the same configuration as that of the measuring unit 21, except that the light-emitting sections 22 a and 23 a emit light in colors different from that of the light-emitting section 21 a. Accordingly, when describing the measuring units 22 and 23 below, the same configurations as those of the measuring unit 21 will be described by using the same reference numbers as those of the measuring unit 21.

The control section 8 includes a CPU 82 and a memory 83 having a ROM and a RAM and controls operations of the various constituent elements of the measuring unit 21. In addition, the memory 83 of the measuring unit 21 stores device information including a device ID 11001 of the measuring unit 21. The memory 83 of the measuring unit 22 stores device information of the measuring unit 22 including a device ID 11002 and the memory 83 of the measuring unit 23 stores device information of the measuring unit 23 including a device ID 11003. Further, the memory 83 stores error IDs which are information for specifying errors.

The LED driving circuit 10 is a circuit for causing the light-emitting section 21 a to emit light in a predetermined color by controlling voltages which are supplied to the LED chips of three colors of the light-emitting section 21 a. The light-emitting section 21 a can display colors which indicate color information stored in the memory 83 by the LED driving circuit 10.

The communication section 9 is, for example, a RS-232C interface, a USB interface or an Ethernet (registered name) interface, and can transmit and receive data to and from the information processing unit 3.

The sensor 11 indicates a plurality of sensors which are provided in the various constituent elements of the measuring unit 21 in order to monitor operation circumstances of the measuring unit 21. For example, in the specimen supply section 4, a sensor for detecting whether or not a pipette is positioned at an initial position and a sensor for detecting whether or not a pipette is positioned at a measurement specimen aspiration position are provided. On the basis of the output of these sensors, the CPU 82 monitors whether or not a pipette has moved to the measurement specimen aspiration position from the initial position within a predetermined length of time.

The specimen supply section 4 includes a pipette for aspirating a sample from a sample container, a mixing container for mixing a sample with a reagent, a pump for supplying a sample and a reagent to the mixing container and the like. The specimen supply section 4 aspirates blood, prepares specimens from the aspirated blood which are to be provided for the measurement of red blood cells, the measurement of platelets and the measurement of hemoglobin, and supplies the prepared specimens to the RBC detection section 6 and the HGB detection section 7. In addition, the specimen supply section 4 mixes the aspirated blood and a reagent (hemolyzing agent, stain solution), prepares specimens which are to be provided for the measurement of white blood cells, and supplies the prepared specimens to the WBC detection section 5.

The WBC detection section 5 is an optical detection section capable of performing WBC measurement (measurement of the number of white blood cells) and DIFF measurement (white blood cell classification). The WBC detection section 5 can perform WBC measurement and DIFF measurement by a flow cytometry method using a semiconductor laser. The configuration of the WBC detection section 5 will be described later in detail. WBC measurement is a measurement operation for counting the number of white blood cells and calculating the concentration of white blood cells in a specimen. DIFF measurement is a measurement operation for classifying white blood cells into lymphocytes, basophils, eosinophils, neutrophils, monocytes and the like and calculating the concentration of each in specimens.

The RBC detection section 6 is a RBC/PLT detection section for performing RBC measurement (measurement of the number of red blood cells) and PLT measurement (measurement of the number of platelets). This RBC detection section 6 can perform RBC and PLT measurement by a sheath flow DC detection method.

The HGB detection section 7 is a HGB detection section for performing HGB measurement (measurement of hemoglobin content in blood). This HGB detection section 7 can perform HGB measurement by a SLS-hemoglobin method.

FIG. 3 is a perspective view showing the configuration of the WBC detection section 5. As shown in FIG. 3, the WBC detection section 5 includes a laser diode 501, a collimator lens 502, a sheath flow cell 503, a condenser lens 504, a pinhole plate 505, a photo diode 506, a condenser lens 507, a dichroic mirror 508, a photo multiplier tube (hereinafter, referred to as PMT) 512, a filter 509, a pinhole plate 510, a photo multiplier tube (hereinafter, referred to as PMT) 511 and amplifiers 61 to 63.

The measurement specimen supplied from the specimen supply section 4 (see FIG. 2) flows through the sheath flow cell 503. The measurement specimen flowing through the sheath flow cell 503 is irradiated with the light emitted from the laser diode 501 via the collimator lens 502. The light (forward-scattered light) scattered forward by the measurement specimen flowing through the sheath flow cell 503 enters the photo diode 506 via the condenser lens 504 and the pinhole plate 505. The light (side-scattered light) scattered laterally by the measurement specimen flowing through the sheath flow cell 503 enters the PMT 512 via the condenser lens 507 and the dichroic mirror 508.

By the irradiation of the light, the fluorescence emitted from the measurement specimen flowing through the sheath flow cell 503 enters the PMT 511 via the condenser lens 507, the dichroic mirror 508, the filter 509 and the pinhole plate 510. The photo diode 506 converts the incident forward-scattered light into electric information according to the strength thereof and outputs the information as the strength of the forward-scattered light. The PMT 512 converts the incident side-scattered light into electric information according to the strength thereof and outputs the information as the strength of the side-scattered light. The PMT 511 converts the incident fluorescence into electric information according to the strength thereof and outputs the information as the strength of the fluorescence. The strength of the forward-scattered light output from the photo diode 506, the strength of the fluorescence output from the PMT 511 and the strength of the side-scattered light output from the PMT 512 are amplified by the amplifiers 61, 62 and 63, respectively, and input to the control section 8.

Basically, each of the measuring units 22 and 23 has the same configuration as that of the measuring unit 21, and thus the description of the configuration of the measuring units 22 and 23, which is the same as the configuration of the measuring unit 21, will be omitted.

In the drawings, for the sake of convenience, the blue color is expressed by the downward diagonal stroke from top left to bottom right, the green color is expressed by the upward diagonal stroke from bottom left to top right, and the orange color is expressed by the vertical line.

FIGS. 6, 7, 8 and 9 are flowcharts showing the processing procedures of the CPU 82 of the measuring unit 21, the CPU 82 of the measuring unit 22 and the CPU 31 of the information processing unit 3 according to this embodiment. Hereinafter, processes of the CPU 82 of the measuring unit 21 and the CPU 31 of the information processing unit 3 will be described.

First, when a power supply of the information processing unit 3 is turned on by the operation of a user, the CPU 31 displays an initial screen 35 a shown in FIG. 11 on the display device 35 of the information processing unit 3 (S2-1). As shown in FIG. 11, in the initial screen 35 a, an icon 821 for displaying a menu screen 211 a of the measuring unit 21, an icon 822 for displaying a menu screen 211 b of the measuring unit 22 and an icon 823 for displaying a menu screen 211 c of the measuring unit 23 are provided.

Next, when the icon 821, 822 or 823 is clicked by the operation of the user, the CPU 31 receives a display instruction of the menu screen corresponding to the clicked icon (S2-2). The CPU 31 retrieves device information of the measuring unit corresponding to the clicked icon from the device information storage section 332, and displays the menu screen 211 a, 211 b or 211 c colorized with a color corresponding to the color information included in the corresponding device information (S2-3).

FIG. 12A is a diagram showing an example of the menu screen 211 a of the measuring unit 21. As shown in FIG. 12A, in the menu screen 211 a, a title bar 91 a, a tool bar 92 a, a function display area 93 a and the like are provided. The title bar 91 a is displayed with a color corresponding to the color information obtained from the device information storage section 332 and a device name is displayed at the left end of the title bar 91 a. In greater detail, the title bar 91 a is displayed with the blue color, and XE-1, which is a device name, is displayed at the left end of the title bar 91 a. In addition, in the tool bar 92 a, a registration button 921, a measurement start button 922, an analysis result button 923, a menu button 924, a state screen button 925 and the like are provided. In the function display area 93 a, a measurement registration icon 931 for displaying a measurement item registration screen 212 a shown in FIG. 15A, a shutdown icon 932, a setting icon 933 for displaying a measurement section setting screen 61 a shown in FIG. 13 and the like are provided.

FIG. 12B is a diagram showing an example of the menu screen 211 b of the measuring unit 22, and FIG. 12C is a diagram showing an example of the menu screen 211 c of the measuring unit 23. Since the basic configuration of the menu screens 211 b and 211 c is the same as that of the menu screen 211 a, a description thereof will be omitted. However, unlike the menu screen 211 a, a title bar 91 b of the menu screen 211 b is displayed with the green color, and XE-2, which is a device name, is displayed at the left end of the title bar 91 b. A title bar 91 c of the menu screen 211 c is displayed with the orange color, and XE-3, which is a device name, is displayed at the left end of the title bar 91 c.

When a power supply of the measuring unit 21 is turned on by the operation of the user, the CPU 82 of the measuring unit 21 transmits the device ID: 11001 which is stored in the memory 83 of the measuring unit 21, reagent information which is installed in the measuring unit 21 and the like as device information to the information processing unit 3 via the communication section 9 (S1-1).

When the memory 83 stores color information indicating the color of the light emitted by the light-emitting section 21 a, the CPU 82 also transmits the color information as device information to the information processing unit 3.

The CPU 31 of the information processing unit 3 determines whether or not the device information has been received via the communication interface 37 (S2-4). When the device information has been received, it is determined whether or not color information is included in the received device information (S2-5).

When the color information is included in the device information, the CPU 31 transmits a device information reception completion notice to the measuring unit 21 (S2-7). When the color information is not included in the device information, the CPU 31 performs a retrieval operation within the device information storage section 332 on the basis of the received device information to obtain the color information which is blue corresponding to the measuring unit 21 (S2-6), and transmits a device information reception completion notice with the obtained color information to the measuring unit 21 via the communication interface 37 (S2-7).

The CPU 82 of the measuring unit 21 determines whether or not the device information reception completion notice has been received via the communication section 9 (S1-2). When the device information reception completion notice is received, the CPU 82 causes the light-emitting section 21 a to emit light (S1-3). When color information is not included in the device information reception completion notice received in Step 1-2, the CPU 82 causes the light-emitting section 21 a to emit light in a color indicated by the color information stored in the memory 83. In addition, when color information which is blue is included in the received device information reception completion notice, the CPU 82 stores the received color information as device information in the memory 83 and causes the light-emitting section 21 a to emit light in blue by controlling the LED driving circuit 10.

The CPU 31 of the information processing unit 3 determines whether or not the measurement section setting screen 61 a shown in FIG. 13 is displayed on the display device 35 (S2-8). When the measurement section setting screen 61 a is displayed, the CPU 31 advances the process to Step 2-11, and when the measurement section setting screen 61 a is not displayed, the CPU determines whether or not a display instruction of the measurement section setting screen 61 a has been received (S2-9). When the display instruction of the measurement section setting screen 61 a has not been received, the CPU 31 advances the process to Step 2-12, and when the display instruction has been received, the CPU displays the measurement section setting screen 61 a (S2-10).

The display instruction of the measurement section setting screen 61 a is issued by selecting the setting icon 933 in the menu screen 211 a of FIG. 12. Also in the menu screens 211 b and 211 c, the display instruction of the measurement section setting screen 61 a is issued in the same manner as in the menu screen 211 a.

In the measurement section setting screen 61 a shown in FIG. 13, a menu tree display area 611 including a device identification item 611 a, a device identification setting menu 612 including color information switching buttons 612 a, 612 b and 612 c and an OK button 613 are provided. In the measurement section setting screen 61 a, the device identification setting menu 612 is displayed by selecting the device identification item 611 a of the menu tree display area 611.

The color change process of Step S2-11 will be described by using FIG. 10. The CPU 31 determines whether or not the setting of color information has been received (S4-1), and when the setting of color information has been received, the CPU updates the color information stored in the device information storage section 332 (S4-2).

The setting of color information is performed in the following procedure. First, when the color information switching button 612 a is clicked, a pull-down menu is displayed. Next, one color information is selected among the color information displayed in the pull-down menu, and the OK button 613 is clicked, whereby the setting of color information is completed. When changing color information of the measuring unit 22, the color information switching button 612 b is used, and when changing color information of the measuring unit 23, the color information switching button 612 c is used.

Next, the CPU 31 changes the colors which are displayed in the screens for the measuring units (S4-3). Here, “the screens for the measuring units” is a generic term including a state screen 71 a shown in FIG. 17 and the screens displayed for each measuring unit. For example, when the color assigned for the measuring unit 21 is changed, the color displayed in the title bars 91 a of the menu screen 211 a shown in FIG. 12, measurement item registration screen 212 a shown in FIG. 15 and analysis result screen 213 a shown in FIG. 16, a title bar 511 a of a measurement section help window 510 a shown in FIG. 14 and an icon 721 of the state screen 71 a shown in FIG. 17 is changed. Since the colors assigned for the measuring units 22 and 23 are changed in the same manner as in the case of the measuring unit 21, a description thereof will be omitted.

Next, the CPU 31 transmits an LED lighting color change instruction including the changed color information to the measuring unit 21 via the communication interface 37 (S4-4).

In FIG. 7, the CPU 82 determines whether or not the LED lighting color change instruction has been received (S1-4). When the instruction has not been received, the CPU advances the process to Step 1-6, and when the instruction has been received, the CPU changes the color which is emitted by the light-emitting section 21 a by controlling the LED driving circuit 10 on the basis of the received color information, and updates the color information of the device information stored in the memory 83 (S1-5).

The CPU 82 determines whether or not the sensor 11 has detected an error (S1-6).
